To wit: There was that time he tried to mack on Mila Kunis, but all she wanted to talk about was then-boyfriend Macaulay Culkin.

This particular story took place around the time Kunis and Brand were filming the 2008 movie 'Forgetting Sarah Marshall' together, and in his free time he hit on her because, hi, this is Russell Brand we're talking about.

"She’s so gorgeous, just so gorgeous and I was chatting her up and got the conversation around to 'have you got a boyfriend,' and then you know that feeling of 'how long do I have to entertain a conversation?'" Brand told the newspaper. "Then I go away and she keeps talking about her boyfriend Mac."

"Eventually she said he’s coming tomorrow and there was some sort of fanfare, she was so excited. Then when he came it wasn’t Mac – it was Macaulay Culkin. He’d got longer and looked pale and scared of himself, like a shaved horse. There was a horror about him," Brand joked.

"I thought, 'You can’t f--k him – that’s the lad from Home Alone!'"

It's not hard to imagine that someday, someone else will hit on her, and he'll tell this exact same story -- only perhaps he'll be horrified the bedmate in question is "the lad from 'Two and a Half Men.'"
